Abstract :
Recently, Hussain et al., discussed the concept of $wt$-distance on a metric type space. In this paper, we prove some fixed point theorems for classes of contractive type multi-valued operators, by using $wt$-distances in the setting of a complete metric type space. These results generalize a result of Feng and Liu on multi-valued operators.
